I have a Bolens ST140 hydro with an Eaton Hydrostatic transmission model 7.
Does anyone know what fluid can be used ?
Can I use automatic transmission fluid or hydraulic fluid ?
I have been told I can use engine oil as long as it is about SAE 20 rating. Does this sound right ?
I would like to find a fluid that is not a special, ie, I dont have to order and wait for for weeks.

Cliff,

Use Mobile One Synthetic oil.

Im not the best with oil types, does the Mobile oil have an SAE rating, or a type that I can trace. ?
